Optical and spectroscopic properties of soda-lime alumino silicate glasses doped with Er3+ and/or Yb

A new set of soda-lime alumino silicate (SLAS) glasses doped with a fixed percentage of ions Er3+ and dierent percentages of Yb3+ was produced by conventional melting process. Their spectroscopic properties, namely absorption and emission spectra, radiative and experimental lifetimes, were measured and are discussed here. Planar and channel optical waveguides were produced in these glasses by ion-exchange, and their characterization is reported as well
